MACHINE FOR NAPPING CLOTH.

SPECIFICATION forming part of Letters Patent No. 484,700, dated October18, 1892.

Application filed February 1, 1892. Serial No. 419,917. (No model.)

To all whom it may concern:

. Be it known that we, GEORGE W. BURR- and MICHAEL MALoNY, both ofWebster, in the county of Worcester and State of Massachusetts, haveinvented a new and Improved Ma'- chine for Napping Cloth, of which thefollowing is a full, clear, and exact description.

Our invention relates to improvements in machines for finishing orraising the nap on woolen or worsted goods, and is especially intendedto be used in connection with the ordinary shearing-machine.

The object of our invention is to produce a simple attachment for ashearing-machine havingoppositely-rotatingnapping-cylinders,

with their needles arranged so as to raise the nap of the cloth bothways at the same time, and also to produce a tension device by means ofwhich the pressure of the cloth upon the cylinders may be easily andaccurately regulated.

Our invention further consists in the peculiar construction of thecylinder-needles; and with the above ends in view it consists in certainfeatures of construction and combinations of parts, as will behereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure l is a front elevation of the machine provided with our improvedattachment. Fig. 2 is a vertical longitudinal section of the same on theline 2 2 in Fig. 1. Fig. 3 is a broken side elevation showing ourimproved attachment. Fig. 4 is an enlarged detail sectional view of oneof the napping-cylinders with a portion of the exterior surface removed.Fig. 5 is a broken plan view of one of the nappingcylinders with theneedles removed, and Fig. 6 is a detail view of a modified mechanism fordriving the cylinders.

The machine has the usual frame 10, like the ordinary shear and giggingmachine, and beneath the main portion of the frame is the customary formof curved bed 11, having a shelf 11 at one end. On the top of the frameare brackets 12, which support the common form of rotaryshearing-cylinder 13, and opposite the shear are the rests or guide-bars14,

over which the cloth runs and which serve to hold the cloth against theshearing-cylinder. The machine has, also, the usual brush 15, arrangedcentrally and transversely therein and mounted on the shaft 16, whichhas pulley 17 at one end and is driven by a suitable driving-belt 18.

The above construction is common to machines of this class and forms nopart of our invention. At the opposite end of the shaft 16 is a pulley19, which connects by means of a belt 20 with a pulley on a shaft 21,which shaft extends transversely across one end of the machine, as shownin Figs. 1 and 2, and carries the upper napping cylinder 22. There aretwo napping-cylinders 22 and 23, placed one above the other, and theseare of exactly similar construction and are held to turn in oppositedirections. Eachcylindercomprises a core 24, a backing 25 for thecylinder-needles, which backing is composed of suitable firm materialand is wrapped spirally about the core, the yielding substance 26 in theform of a fabric, which is wrapped exteriorly and spirally upon thebacking 25, and the needles 27, which are held in the material 26 andthe inner ends of which rest upon the backing 25.

The needles 27 are features of our invention and are of commoncarding-wire, but are bent back slightly at the point where they leavethe material 26, and the ends of them are ground forwardthat is, in thedirection in which the cylinder rotatesso as to produce short sharphooks, as shown in Fig. 4, which hooks serve to raise the nap of thecloth. The napping-cylinders are geared together at one end, beingconnected by the gear-wheels 28, which causes them to rotate in oppositedirections, the said short sharp hooks of both cylinders projecting inthe direction of rotation thereof, thus raising a nap both ways on thecloth. The napping-cylinders may, however, be driven by any suitablemechanism, and another form of driving mechanism is shown in Fig. 6,where the upper cylinder is provided with a pulley 29, the lowerone witha pulley 29, and a pair of pulleys 30 are mounted in a bracket 31, theirshafts being held to slide in the slots 32 in the bracket and beingsecured in place by suitable nuts 324. The pulleys 30 are arranged belowthe napping-cylinders, and a continuous belt 33 runs over the pulleys29, and 29 and beneath the pulleys 30.

The machine has at the end opposite the napping-cylinders the usualguide-roller 34, with the small guide-bars 35 at each side thereof, aguide-roller 36 near the upper end of the machine and above theguide-roller 34, the guide-roller 37, arranged near the top of themachine and between the shearing-cylinders 13 and the brush 15, so as tohold the cloth to the brush, guide-rollers 38, arranged parallel witheach other and beneath the brush 15, so as to enable the cloth toproperly pass the brush, a guideroller 39 in advance of the rollers 38and a little above the same, a guide. roller 40, arranged beneath thelower cylinder 23, and a tension-roller 41, arranged be tween the planesof the cylinders 22 and 23 and a little in advance of them, this rollerforming part of our invention.

A guide-roller 42 is mounted above the upper cylinder, a guide-roller 43on the top of the frame and in the rear of the roller 42, a guide-roller44 in advance of and a little below the roller 43, a guide-roller 45above and in advance of the roller 44, and the usual swingingguide-frame 46. These guide-rollers are arranged substantially as in theordinary machines of this class and form no part of our invention; butthe tension-roller 4.1 is an important feature of the invention, as byit the pressure of cloth upon the nappingcylinders may be nicelyadjusted. This roller 41 has its ends journaled in rack-bars 47, whichbars are held to slide horizontally in keepers 48, secured on the innersides of the main frame, and the inner ends of the rackbars engagepinions 49 on a transverse shaft 50, which shaft is journaled insuitable supports on the main frame and carries at one end a bevelgear-wheel 51, which meshes with a bevel-pinion 52 on the end of a shaft53, the latter being mounted in keepers 54 and extending longitudinallyalong one side of the machine, the shaft terminating at one end in ahand-wheel 55, by means of which it may be turned, and by turning theshaft 53 the shaft maybe also turned, so as to cause the pinions 49 toact on the rack-bars 47 and 50 either advance or retract thetension-roller 41, so as to regulate exactly the pressure of cloth onthe napping-cylinders.

The cloth 56 is fed to the shearing-cylinder 13 in the usual way, andfrom thence passes downward over the roller 37, beneath the brush 15,being operated on by the brush, thence beneath the parallelguide-rollers 38, over the guide-roller 39, beneath the guideroller 40,thence upward in front of the napping-cylinders and in contact with thetensionroller 41, thence in front of the roller 42, up

over the roller 43, beneath the roller 44, and

over the roller 45 to the shelf 11 of the bed 11.

ping-cylinders having needles inclined in a direction opposite to theirdirection of rotation and terminating in burrs or points ground on theends thereof and projecting at an angle therefrom in the direction ofrotation of said cylinders, of mechanism for rotating the cylinders inopposite directions, and suitable guides for holding the fabric inproper relation to said cylinders to be acted upon by said burrs orpoints, substantially as set forth.
